摘要： An arc discharge headlamp system employs a single continuously operating arc discharge source to provide both high and low beam patterns. The continuously operating arc discharge increases lamp life and eliminates the problem in arc light source headlamp systems of momentary dimming when switching to high beam operation due to mercury condensing within source. The headlamp has an arc light source mounted horizontally within a reflector. Light from an arc light source is reflected by the reflector through a lens to form a low beam pattern. A mirror within the reflector is positioned to form a virtual image of the light source and which is directed towards a second lens concentric with the first lens to form a high beam pattern when combined with the low beam pattern. Switching between the high beam and low beam patterns is accomplished in a variety of ways. In the preferred embodiment, the second lens incorporates an electrically responsive light valve which either passes or blocks the virtual image of the arc light source. Alternatively, the mirror may be moved between a position that directs the virtual image through the lens to a position where the virtual image is not directed through the lens. Rather than moving the mirror, it may be blocked with a mask during low beam operation.

摘要： A xenon metal halide lamp having an improved electrode structure that is particularly suited for automotive applications is disclosed. The electrode is comprises of a tip portion that is located at one end of a shank with the shank having a filament coiled therearound. The tip and shank portions are designed to allow for high initial current during starting and low current during operation. The coil filament is situated in opposite neck portions of an envelope forming the light source so as to; (1) cause the electrodes to be axially aligned within the light source; (2) keep the shank of the electrode from intimate contact with the envelope thereby preventing the condensation of the mercury and allowing for substantial vaporization of the metal halide ingredients at the neck portion; and (3) prevent the thermal expansion of the electrode from cracking the envelope.

摘要： A lighting subsystem is disclosed that uses optical devices to alter, the actual or apparent optical position of the ends of optical fibers coupled to a high intensity light source so as to provide all of the forward illumination needs for a vehicle. In one embodiment, optical wedges are interposed between a rectangular array of optical fibers and an array of lens elements mountable on the front of a vehicle from which the forward illumination is transmitted therefrom. The imposition of the optical devices alters the actual or apparent optical position of the fibers relative to the lenses and thereby changes the forward illumination from its low to its high beam pattern, to a fog beam illumination or to a cornering illumination pattern. In another embodiment, flat shaped optical members are rotated to provide the various forward illumination needs of the vehicle.

摘要： Disclosed is a xenon lamp used for lighting applications and which is particularly suitable for automobile applications such as headlamps. The benefits of such usage, relative to incandescent lamps commonly employed for automotive forward lighting applications along with discharge lamps for lighting application, are primarily related to the size, shape, quality and concentration of the light generated by the xenon lamp and the ability to selectively move the position of the generated light relative to the reflector in which the xenon lamp is housed. The xenon lamp also provides the ability for the light to be generated by excitation of a D.C. source so as to be first positioned relative to the reflector to serve as the light source for low beam applications and then moved to a second position relative to the reflector to serve as the light source for high beam applications.

摘要： A ballast circuit arrangement for providing a predetermined desired A.C. voltage to enhance the operation of the gas discharge tube serving as the main light source in a lighting unit of the type which also comprises an incandescent filament serving as a resistive element and a supplementary light source is disclosed. The circuit arrangement operates directly from an applied 220 volt, 50 Hz or 120 volt, 60 Hz alternating current (A.C.) voltage source. The circuit arrangement comprises a capacitor connected serially with both the incandescent filament and the gas discharge tube. If desired, the incandescent filament may be replaced with a resistive element. The value of the capacitor is selected so as to reduce the applied 220 volt, 50 Hz or 120 volt, 60 Hz A.C. source to a desired range for operating the circuit in a manner to develop a desired reduced voltage for operation of the gas discharge tube. The reduced operating voltage correspondingly reduces the restrike voltage that may be necessary to operate the gas discharge tube during restrike conditions. The reduced operating voltage of the gas discharge tube readily allows for the development of the restrike voltage directly available from the typical 220 volts, 50 Hz or 120 volts, 60 Hz A.C. source. The circuit arrangement further provides for an automatic restrike voltage under reduced voltage A.C. source conditions.

摘要： An optical coupling assembly is useful for coupling a source of light, having high brightness and focussed at a focal plane, to a plurality of optical light conductors. The coupling assembly includes a light transmissive elongated segmented rod-shaped coupling member formed of a plurality of longitudinal sections and a retainer member for holding the longitudinal sections together in an assembled relationship. The coupling member has a central longitudinal axis and at an input end is disposed at the focal plane of the light source, while at an output end is disposed against leading ends of the plurality of optical light conductors. Each longitudinal section of the coupling member has a plurality of spaced longitudinal surfaces capable of internally reflecting light traveling within the longitudinal section. The retainer member is a hollow sleeve which holds the longitudinal sections together in the nested relationship with one another such that some of the longitudinal surfaces of the longitudinal sections define an external circumferential surface of the coupling member whereas others of the longitudinal surfaces of the longitudinal sections define a plurality of internal surfaces within the coupling member which extend from the external circumferential surface to the central longitudinal axis thereof.

摘要： A liquid crystal display (LCD) is provided with a source of backlighting which augments reflected incident light to provide increased contrast. A liquid crystal cell which does not contain dye, but becomes clear when a field is applied, is sandwiched in back of a liquid crystal cell with a dye and electrically connected so that when the front liquid crystal cell is turned ON to make selected portions of it transparent, the back liquid crystal cell is OFF so that corresponding portions of it are highly reflecting. No voltage is allowed to be applied across nonselected portions of the front liquid crystal and a voltage is applied across corresponding nonselected portions of the back liquid crystal making the nonselected portions of the back liquid crystal clear, producing a display of high contrast. Sandwiched to the rear of the back liquid crystal cell is a clear plastic wedge which is edge lighted. The edge lighted wedge only appears bright in the areas where the voltage on the back liquid crystal cell is OFF or not applied thereto.

摘要： Miniature high pressure arc lamps containing a substantial pressure of xenon, in addition to metal halide and mercury, can provide instant light at turn-on and are suitable for automotive headlamps. The high pressure of xenon aggravates convection which causes arc bowing and overheating of the envelope above the arc. By operating the lamp at high frequency within selected bands, acoustic modes are excited in the fill which straighten the arc and make the envelope more isothermal. Frequency modulation of the input can be used to broaden the band selected for acoustic operation and relax the tolerance on arc tube and circuit parameters needed for a match. Acoustic operation may also be used to effect physical displacement of the arc for beam switching.
